Buffalo Wild Wings franchisee: cluster outbreak signal arrived 36 hours before the FNOL did

Synthesized by Claude Opus 4.8 from 3 signals

Minerva flagged a Yelp star-average drop from 4.2 → 2.6 across 11 reviews at the Southfield BWW, with repeated mentions of 'food sat out' and 'closed early.' Two foodborne-illness complaints surfaced on Google reviews 36 hours before today's first formal FNOL — patron alleging norovirus-style ER visit Saturday night. Local health department isn't yet engaged. LinkedIn shows headcount down 27% in 60 days, concentrated in line-cook roles. Owner Selene Kowalczyk's social sentiment shifted from neutral to -0.91 over 30 days with explicit posts about 'insurance is killing us.' If this becomes a multi-plaintiff outbreak — and the pattern suggests it might — the GL severity here moves from a $40K nuisance into a six-figure aggregation event. Pre-position the cluster watch now.
